LT-Series Hydraulic Excavators are manufactured by our LUTONG GROUP according to the international advanced technology, consisting of a boom, stick, bucket and cab on a rotating platform (known as the "house"). The house sits atop an undercarriage with tracks. All movement and functions of this hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors. The diesel engine and key hydraulic components adopt the famous international Brands. This Mini Hydraulic Excavator is your ideal equipment to choose, we offer you not only the products with reasonable price, but also our professional after-sale service and our favorable spare parts timely.

 

LT-Series Hydraulic Excavators can be used in many ways:

1. Digging of trenches, holes, foundations  

2. Material handling  

3. Brush cutting with hydraulic attachments  

4. Forestry work  

5. Demolition  

6. General grading/landscaping  

7. Heavy lift, e.g. lifting and placing of pipes  

8. Mining, especially, but not only open-pit mining  

9. River dredging  

10. Driving piles, in conjunction with a pile driver

LT-Series Hydraulic Excavator capabilities have expanded far beyond excavation tasks with buckets. With the advent of hydraulic-powered attachments such as a breaker, a grapple or an auger, our excavator is frequently used in many applications other than excavation. Our excavators feature a quick coupler for simplified attachment mounting, increasing the machine's utilization on the job site.
